To aZZ whom it mayconcem: Be it known that 'LPETER useful improvements in qVac'zuuin-Liiiings' for BOX-Cars and the like; and I do' declare V the following to be a full, clear, and exact description of the invention, such as will enlll able others skilledl in the art to which it ap- 'pertains to make and use the saine.-

lady inven ionhas for its object to provide a simply constructed vacuum lining which I may be easily applied to all classes of closed ears, storage rooms and the like without the necessity of altering them 1n any manner whatsoever, the 'provision of the lining serving to Aexclude both heat in summer and cold in winter, thus making it `only necessary to Warm or chill the interior of the car or the, .a

by blocks 4 of Wood'or the like, said-blocks-- like by the use of air currents, instead of usine; agreat amount oice or fuel.

With the foregoing object in view, tlle i'nvention resides in the novel features of construction and arrangements of parts hereinafterl fully described and claimed, the de scri'ptive matter being supplei'nented` by the accompanying drawings which forma part of this specification and in whichz.

invention applied to a boxrcar for illus.-

trative purposes, but I. wish it understood that it is equally,y well applicable for vreihigcrater and insulated cars, also storage robnis' which perishable goods are and the like in plurality of rectangular sections 1 which are disposed edge'to edge and providedat' the edges of the-#Hoor F with channels'2` opening upwardlyfseeFigs. 1, 2, 3, 4, and 5').4

As detailed 'more particularly in Figs. l and 5, eachsection .l isoi hollow formation, be gng formed of a pair o-'metal plates 3 suit# sealed at their ledges and spaced apart from one or botli'of the plates 3 and received in .sockets 6- formedl in the blocks. At theends of the sections 1, the metal is suitably Positioned against the sides cally disposed rectangular sections 7v disposed edgeto edge with their lowcrends receved snugly in the grooves SZ as' featuredlmost clearly in Figsl and- 3the lower ends of said sections ljbeing by.preference`slightly reduced in thickness as shown vat 8. Like the floor sections '.1, the vside sections-74 are formed of spaced plates lheld in spaced re-v 7 disposed against the inner sidesof the car ends E and thus the outermost of the sections 7 are retained in place. Preferably, the metal on the outer-edge of the outermost sections 7 a is extended to provide achaimel to receive the 'endniost 'edge of sections 7,

ls of esta j C and locatedat opposite sides of the door openings O, are side linings formedof vertir 'lation by blocks L@which are retained in 4SIS thus providing 'greater stability. In the .I

drawings l have shown sections 7 as identical in construction with sections 7, with this exceptm-n, said sections 7 being provided on 55 f tions being in pa-rtnlield in jglace bysaid their upper ends with channels 9F as seen in' Fi.1. 1. *1 r o secure the side sections 7 in place at opposite sides of the door openings O, horizontally elongated key sections 1Q are 1o cated at the upper'ends of said openings and secured in plaie'by screws or the like 11,

. said keysections'lsoserving to prevent re-' edges of these sections are not provided with most sections 1 of the licor lining.

channels such as those described in connection with the others. The outer edges of the endmost sections 13 are received snugly in the channels 9 and the end sections 7A abut the upper ends oi. said last named sections, being t-hus effectively secured in place, the lower ends thereof being held against displacement of the channels 2 of the end- The sections 13 are disposed at opposite sides of the openings O and have their ends received in the channels 9 ofthe Side sections Z (see Fig. 3). By this arrangement, the sections. 13 are not only supported by thesections 7, but they retainthe upper ends of the latter in place, while thelower ends of said side sections 7 are maintained in properposition by the channels In order to remove any of thcsections 13, it is. necessary to. move them vinto a predetermined area, that is thearea directl above the door opein-l ings O, whereupon t ey are free tomove downwardly, provided the key sections l0 mally occupying the arca in arc .first removed. vTo normally prevent movement of the ceiling sections 13 into the aforesaidarea, one or more additional key sections` 1G are provided, said sections n0rquestion ,as shown in Fig.. 1. The key sections '16l are supported and held in place by the'key seotioiis 10 above described, and the fastening means 11 employed for the latter/nite theV` only fasteners necessary to retain'tlic'entiref lining `in the car.

In applying the lining. the floor sections 1 are first laid in place, after which the end and side sections arewzpplied, said endsec# side sections a's above'describedi.

The ceiling 1 of the-side and end sections in place. 'The key sections 16 are new applied toiretain .the ceiling sections 13 in operative' position,

and when the other key sections 10 are'now by the being started "like having a' door or; other'op -tlie entire lining isjlield the in the re` quired manner. 'Ihe door lininlgvqiaybe secured to the vdoors D byan f--prefened Fig. 1.

of. cars, the endmost loor sections Inay be provided with removable portions 1? -tobe removed when repairing thedraft rigging.

From the foregoing, taken in connection with the accompanying drawings, itwill be seen' that I have provided a novel and very advantageous lining which may be secured in place within a rooin,-box car or the like,

provision of certain key sections which alone must be anchored. A great saving isthus eccted in nails, 'screws and the like, andremoval of one or more sections .at any time for repairs, is a simple matter, 'as is also the substitutionof a new section for one that has become damaged;

The several holloiv sections of the lining by preferencek contain partial vacuums, sincev this 'is the mostl eiiicient insulatonagainst 9G both cold and heat, but'I Wish it understood that if it is found desirableto packsaid sections with insulating'material 'this-.may well .be done. In all cases, the linmgwill serve to exclude eitherliot or cold temperatures to advantage 4'It is thus unnecessa to provide 'refrigerating or heatin systems for cars which are to carry perisha Vle goods i in -winter'or summer,.siiiee after the interior of the car is either chilled or heated before 'on its route, the temperature will reninin vsubstantially the same. 1

Since probably the best tained from theseveral features shown and results are ob#l 'iet described, they are by preference followed,A

but within the scope of the invention as' be-fmade.
